Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A semiconductor device comprising: a pixel comprising: a light-emitting element; a transistor; a first capacitor; a second capacitor; and a third capacitor, wherein one of a source and a drain of the transistor is directly connected to a first electrode of the light-emitting element, wherein the other of the source and the drain of the transistor is electrically connected to a first wiring, wherein a first terminal of the first capacitor is directly connected to a gate of the transistor, wherein a first terminal of the second capacitor is directly connected to the one of the source and the drain of the transistor, wherein the transistor comprises a source region and a drain region in a semiconductor substrate, wherein a second terminal of the second capacitor is electrically connected to a second wiring, wherein a first terminal of the third capacitor is electrically connected to a second terminal of the first capacitor, and wherein a second terminal of the third capacitor is electrically connected to the second wiring.

2

2. The semiconductor device according to claim 1 , wherein the second terminal of the first capacitor is electrically connected to the other of the source and the drain of the transistor.

3

3. The semiconductor device according to claim 1 , further comprising circuits configured to input an image signal to the pixel so that variation in mobility of a transistor of each pixel is compensated.

4

4. The semiconductor device according to claim 1 , further comprising a first switch, wherein the one of the source and the drain of the transistor is electrically connected to the light-emitting element via the first switch.

5
